This invention relates to filling apparatus with particular reference toliquids to be transferred to bottles, jars and other vessels.

In apparatus of this type, the liquid controlling valves are operated bya transmission mechanism producing an intermittent motion whereby thevalves are alternately caused to open and close to allow for-timeconsumed in changing from filled to the next succeeding empty vessels.

The transmission mechanism preferably includes change speed gearing incontinuous motion, whereby the length of the filling periods can bevaried without materially affecting the time allowed for changing thevessels between the filling periods.

One of the objects is to provide apparatus for filling with regulatedquantities. 7

Another object is inthe provision of an apparatus capable of filling aplurality of vessels simultaneously.

A further aim is to provide means whereby each nozzle intermittentlypartially fills the Y vessels, so that the same may be conveyed at asteady rate.

A still further characteristic is in the provision of means for applyingheat, thus enabling the steady flow of thick or dense liquids.

These and other objects,'which will become apparent as the descriptionprogresses, are accomplished by the novel construction, combination andarrangement of parts, hereinafter described and illustrated in theaccompanying drawings, forming an important component of thisdisclosure, and in Which Figure l is a partial side elevational, partialtransverse sectional view taken on line 1-1 of Figure 2.

Figure 2 is a front elevational view of an embodiment of the invention,as disclosed herein.

In the drawing, the numeral 5 generally designates a rectangular basehaving bearings 6 spaced along the front edge thereof, in which isjournalled a shaft 7.

Mounted on the shaft intermediate the bearings is a pair of spacedsprockets 8 connected by chains 9 with similar sprockets 1O '50 fixed ona sleeve ll'rotatable on a shaft 12 1927. Serial No. 172,959.

journalled in bearings 13 rising from the base 5.

Loose on the shaft 12 is a pair of sprocket wheels 14 connected bychains 15 with larger sprockets 16 fixed on a shaft 17 j ournalled inthe lower bearings 18 of a support 19 suspended from the ceiling.

Looselymounted on the shaft 17 is a gear 20 and a pinion 21 meshingrespectively with a pinion 22 and a gear'23 fixed on a shaft 24journalled in the upper bearing 25 of the supports 19, the shaft 24being positively driven by a mechanism (not shown) in a continuousmotion.

Keyed on the shaft 17 and slidable thereon intermediate thegear 20 andpinion 21 is a disc 26 provided With a groove 27 in its peripheralsurface, the groove being engageable with a pin 28 fixed in a lever 29pivoted at 30.

'The disc26 is also provided with pins 31 on both sides selectivelyengageable with pins 32 and 33 respectively fixed on the adjacentsurfaces of the gear 20 and pinion 21.

-Thus, by moving the lever 29 so that the pins 31 engage the pins 33,the gear 23 driving the pinion 21,-will' through the disc 26, drive theshaft 17 at high speed.

Also,'by moving the lever 29 so that the pins 31, engage the pins 32,the pinion 22 driving the gear 20, will, through the disc 26, drive theshaft 17 at low speed. s 7

Fixed on the shaft 17 intermediate the sprockets 16, are similarsprocketwheels 34 connected by chains 35 to like wheels 36 looselymounted on the sleeve 11, the chains carrying at regular spacedintervals between them, a plurality of bars 37 adapted to engage lugs 38formed 'on the sleeve intermediate the wheels 36.

Formed on the base 5 in the rear of the bearings 6, are correspondingbearings 38 in which is journalled a shaft 39.

Fixed on the shafts 7 and 39- are rolls 40 over which'is trained anendless conveyor belt 41, the same being further supported by aplurality, of rollers 42 journalled in side supports43, so that theweight of the containers- 44 carrying the receptacles 45 to be filled,

will be firmly sustained. v

Slidably keyed on the shaft 12 intermediate the bearings 13 and wheels14, are discs 46 provided with grooves 4'? and pins 48 engage able withpins 49 on the outer faces of the wheels 14; the grooves 47 engagingpins 50 fixed on levers 51 pivoted at 52 to a cross-support 53 betweenthe vertical supports 54. i

The shaft 12 extends outwardly, entering a casing 55 inwhich are t'anks56, and below them are a pair of square chambers 57 at right angles eachhaving a cylindrical'nozzle 58 extending downwardly 'from its inner openend, the tanks 56 being connected at their lower portions by pipes 59 tothe inner ends of the chambers 57. I 7

The upper wall of ea'chchamber is lined with a rubber packing 60 andslidable inthe chambers are pistons 61 connected by links-62 to flatrectangular slides 63 movable over guide plates-64011 the lower centralwall of the casing 55 intermediate tile nozzles 58, the platesbeingrecessed to receive rubberpackings 65 between them and the casingwall and the pistons'are also recessed to receive rubber packings 66. v

The plates 64 are formed on cam brackets in which are operable cams 68fixed on the shaft 12.

Passing over the casing 55 are substantially W-shaped pipes69 throughwhich steam-is forced to ;keep the substance contained inthe tanksbGfrom becoming thick or dense, and by so doing prevent clogging of theappaatu Thus in operation, motion is transmitted from the drive shaft2-24 to the shaft at either high speed or low speed depending upon theengagement of the disc clutch 26.

Throughthe bars 37 ofthefchain 35, lugs 38, wheels lO 'and chains 9, theconveyor belt 41 is actuated intermittently, although the machine driveis continuous. 7

Simultaneously, the shaft 12 is rotated,

through the chains 15, wheels l-4 and the discs 46 which action,throug-hthe cams 68, actuates the pistons 61 so that when a container 45 isunder the nozzle58 the piston61 moves toward that nozzle to force theliquid, from the tank56 to thechamber 57, into the container;and as thepiston moves forward it closes thepipe 59 stopping the flowof-liquid. Bythis time the container 45 is filled and the conveyor moves it on-sothat when the piston starts again, the next container 45 will be in aposition beneath the nozzle.

Thus by thereciprocating motion of the pistons and the conveyor thecontainers are alternately filled and then carried away.

it may be seen that the quantity of the liquid allowed to flow may beregulated by the speed of the cams --68 and these in turn controlledbythe lever 29, V

Although the foregoing is descriptive of the preferred--embodiment ofthe invention, it will be apparent that-minor changes may be made in-itsconstruction, without I the exopposed apportioning chambers therebelow,

valves movable in said chambers, looped brackets connecting said valvesin paired relati'on,1a shaftrevoluble in said tank, cams on said shaftengaged in said brackets to reciprocate said-valves, and tubularconnections between said chambers and tank controlled by said valves.

'2. An apparatus for supplying containers withliquid comprising a tank,a series of opposed apportioning chambers there'below, said chambersbeing rectangular in cross section, Valves connected in paired relationoperative in said chambers, packings in the upper portions of saidchambers to contact the upper surfaces of said valves, other packingscarried in the lower surfaces of said valves to contact the lowerportions of said chambers, a constantly rotating shaft passinglongitudinally through said tank and cams :fixed on said shaft to causesaid valves to move reciprocatively at regular intermittencies.

In testimony whereof I have signed my name to this specification.
